What are the Newton's laws of physics?

* Newton's First Law of Physics.
An object in motion will remain in motion and an object
at rest will remain at rest unless acted upon by an outside force.
* Newton's Second Law of Physics.
The net force of an object equals it's mass times it's
acceleration.
* Newton's Third Law of Physics.
When one object exerts a force upon a second object, the
second object exerts an equal and opposite force upon the first object.
